I gotta agree with Golgo here. I haven't even seen this movie yet but the whole, "I want your healing factor and i've found a way to get it" is just too close to the cure storyline in my opinion.
For me i've already seen one X film dealing with mutants losing their powers and one film with that vibe is enough for me.
For this movie not even to mention the cure seems like ignoring the ten thousand pound elephant in the room,but to be honest i'm not a huge fan of the whole loss of power stories. Too many of them (especially in the movies).

Thank You. I'm not saying the whole movie should be an extension of the cure storyline, all i'm saying is since the cure was such a BIG DEAL, and it was big news a year ago when Yashida started looking for Logan, it not being mentioned in mere passing conversation as kinda weird.
